Aggregate gradation refers to the distribution of particle sizes within a given sample of aggregate material, which significantly influences the properties and performance of construction materials like concrete and asphalt. Proper gradation ensures optimal packing, workability, and strength of the composite material, reducing voids and enhancing durability.

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement that hardens over time, widely used in construction due to its durability and versatility. Its properties can be modified by altering the mix proportions and using various additives to achieve desired strength, workability, and resistance to environmental factors.

Asphalt is a sticky, black, and highly viscous liquid or semi-solid form of petroleum used primarily for road construction, where it is mixed with aggregate particles to create asphalt concrete. It is valued for its durability, waterproofing properties, and ability to withstand heavy traffic loads, making it essential for modern infrastructure development.
